Universal Connector Switching for Server Module Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-density servers with multiple modules require complex designs and increased manufacturing costs due to the need for various types of connectors for CPU and expansion modules, limiting expandability and increasing production expenses.
Innovation Solution
A computer system with a first module, a second module, and connectors that include a switch to control data transmission lines, allowing the first module to connect to either the first or second module, enabling flexible expansion and independent operation without dedicated connectors for each module type, thus simplifying design and reducing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different types of connectors are used for CPU module and expansion module, then module identification and control are facilitated, but design complexity and manufacturing cost increase
Solution Approach 1:
The patent employs a universal connector design where the same connector type is used for both CPU modules and expansion modules. The connector includes multiple electrodes that can handle different signal types (control signals, data signals, power signals) depending on the module connected, eliminating the need for physically different connectors for different module types.
Solution Approach 2:
The connector is designed with different electrodes serving different functions: some electrodes are configured to transmit control signals when a CPU module is detected, while other electrodes transmit data signals when an expansion module is detected. This local differentiation within a uniform connector structure enables module-specific functionality without requiring different connector types.
2Adaptability or versatility
If different types of connectors are used for CPU module and expansion module, then module-specific control is enabled, but manufacturing cost increases
Solution Approach 1:
By using a single connector design for both CPU and expansion modules, the manufacturing process is simplified. The uniform connector structure can be mass-produced using the same tooling and processes, reducing tooling costs and assembly complexity while still supporting different module types through electronic configuration rather than physical differentiation.
Solution Approach 2:
The patent merges the functionality of what would traditionally require separate connectors into a single unified connector design. This consolidation reduces the variety of components that need to be manufactured and stocked, simplifying the supply chain and reducing manufacturing overhead while maintaining the ability to provide module-specific control through software or control logic.
3Manufacturing precision
If dedicated connectors are used for each module type, then control precision is improved, but expandability is limited
Solution Approach 1:
The universal connector design maintains control precision by including dedicated control signal electrodes that are activated based on the detected module type. The connector can precisely control CPU modules when they are inserted, while simultaneously supporting expansion modules with appropriate data signal transmission, all through the same physical interface.
Solution Approach 2:
The connector system dynamically adapts its signal transmission characteristics based on the type of module detected. Control signals are routed appropriately based on whether a CPU module or expansion module is present, allowing the system to maintain precise control for CPU modules while enabling expansion functionality when expansion modules are detected, without requiring pre-configured dedicated connectors for each scenario.
Data Source
AI summary
A computer includes a first module, a second module controlled by the first module, a first connector connectable to the first module, a second connector connectable to either the first module or the second module, and a data transmission line configured to connect the first connector to the second connector. The first module includes a switch configured to electrically connect the data transmission line to the first module attached to the first connector. The switch breaks an electrical connection between the data transmission line and the first module attached to the second connector. Thus, it is possible to improve expandability in the computer acting as a server. Additionally, it is possible to prevent complexity of design and increased cost in manufacturing servers.
